hi my regal tang and my foxface have whitespot i have used esha oodinex in my tank the last 3 days ...the tang looks worse now i havent got a quarantine tank so thats out of the question..what else can i do im at my wits end HELP.......

You can add a very large UV system and feed them vitamin enhanced foods plus do lots of water changes to keep it at bay but sooner or later its going to get them. They may develop an immunity for 6 months or so if you manage to keep them alive long enough, but it wont last.

Get down to the supermarket and buy a large plastic container to set up as quarantine, use amguard to detoxify ammonia and a normal internal filter like a fluval 3+ or aquaball. A few plastic pipes can give the fish cover for security.

There is no reason they wont provided you caught it and treat them early enough. My regal tang and clown have had white spot and worse all at once and survived.

You have to quarantine and treat all the fish as they will all be infected even if they don't show it. You will also have to leave the display tank free of all fish for 4-8 weeks to ensure all the Ich in the tank die off naturally before adding fish back in. Keep the equipment from the quarantine tank away from the display tank too so as to avoid cross contamination.

If you only treat only some of the fish or don't leave the display tank fallow long enough they will simply get infected again as soon as you stop treatment.

If it helps any, get some 25L containers from the supermarket and drain some water into them so you can move your rocks and coral over, once thats out the way drain some more water (you can use this water for your QT) and use two nets or a net and a glass jug. Slowly coax the fix into the net.Once the fish are in quarantine you've got 4 weeks to set the rocks and corals up again how you like them.

the white spot has gone, i went away for a few days came back sunday with the task of setting up a quarantine tank on the monday and the white spot had gone the regal was coverd two days before...i have been feeding with garlic brineshrimp every morning and bought a cleaner wrasse yesterday so at present everything is ok...thanks

Good news It wasn't white spot if it went away like that, Regal's can develop white spots from nutritional deficiencies similar to acne I guess! They need a meaty vitamin rich food, although neither brine shrimp or garlic are ideal as neither is a natural source of food for them. I do feed mine vitamin enriched brine shrimp on occasion.
